applyFileRenamesToArgs is not working in Run script Post Action

dotnet CLI (dotnet new)

Describe The Bug

I'm encountering an issue with the .NET template engine where applyFileRenamesToArgs does not properly substitute the symbol values for ServiceName and ServiceType within the args of a post-action. I want to pass these parameters to a PowerShell script, but the symbols remain as placeholders (ServiceName}, {ServiceType) rather than being replaced with the actual values input by the user.

Expected Behavior: When using applyFileRenamesToArgs, I expect the symbols specified (ServiceName and ServiceType) to be replaced with the actual values provided by the user during template instantiation.
Template instantiation - example: dotnet new microservice -n TypeTest.MyServiceTest --ServiceType TypeTest --ServiceName MyServiceTest
Post-Action run script - example: powershell -ExecutionPolicy Bypass -File ./Create_file.ps1 TypeTest MyServiceTest

Actual Behavior: The placeholders {ServiceName} and {ServiceType} are not replaced with the user-specified values and are passed to the PowerShell script as literal strings instead.
What I have:
Template instantiation - example: dotnet new microservice -n TypeTest.MyServiceTest --ServiceType TypeTest --ServiceName MyServiceTest
Post-Action run script - example: powershell -ExecutionPolicy Bypass -File ./Create_file.ps1 ServiceType ServiceName

To Reproduce

1. In template.json
   create symbols and postAction run script

 "symbols": {
    "ServiceType": {
      "type": "parameter",
      "description": "e.g., Frame, Application, Service",
      "replaces": "ServiceType",
      "datatype": "text",
      "fileRename": "ServiceType",
      "defaultValue": "ServiceType"
    },
    "ServiceName": {
      "type": "parameter",
      "description": "Name of the project",
      "replaces": "ServiceName",
      "datatype": "text",
      "fileRename": "ServiceName",
      "defaultValue": "ServiceName"
    }
  },
"postActions": [
    {
      "actionId": "3A7C4B45-1F5D-4A30-959A-51B88E82B5D2",
      "description": "Create .bicep",
      "continueOnError": true,
      "applyFileRenamesToArgs": ["ServiceType", "ServiceName"],
      "args": {
        "executable": "powershell",
        "args": "-ExecutionPolicy Bypass -File ../Create_file.ps1 \"${ServiceType}\" \"${ServiceName}\""
      }
    }
  ]

Generate project with standard command with --ServiceName and --ServiceType:

example: dotnet new microservice -n TypeTest.MyServiceTest --ServiceType TypeTest --ServiceName MyServiceTest

3. There will be command from args from post-Actions with non-changed arguments.

Additional context

Is my postAction correct?
How should I pass those arguments ?

I also tried to put "applyFileRenamesToArgs": ["ServiceType", "ServiceName"], inside args.. but still it didn't work.
